In order to mine using your phone you need a phone with Octocore or greater chipset. But the thing is it will ruin your phone. Your phone might overheat as it uses a lot of memory and processor. It might end up destroying your own phone. And the price? I guess you will earn only a cent for a 3 days non stop mining. Its a waste of time.
Is mining with mobile device a profitable venture today? I read a bit about this and learned that Monero maybe worth mining. then there's Electroneum as well. I wanted to know from other's experience.
One might ask why spend on buying phones. Instead get a PC. Thing is I have few old phones that I can't sell, I want to see possibility of getting some cost back before giving/throwing them away
